Abstract：The authors explained the application effect of the soil geochemical survey in the tropical arid steppe landscape area of Botswana,exemplified by the prospecting in Tonota-Foley, within central area of Botswana. By using this method, the authors delineated 17 geochemical composite anomalies in Tonota-Foley and found that the sources of anomalies are calcite serpentine, as evidenced by trenching in the typical anomaly areas. It is shown that soil geochemical survey, which is accurate and effective in delineating anomalies, is suitable for the landscape of the central area of Botswana. This method can be extensively employed in similar landscape areas of Botswana.
